--- Comment #31 from Hans-Peter Nilsson <hp at gcc dot gnu.org> --- Created attachment 44851 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=44851&action=edit patch as per directions Thanks. I also adjusted include/std/atomic, without which the struct X test-case would not be impacted; only "base integral types". I hope 54005.cc contains sufficient variety, please advise if not. Will post this to lists after testing.
